Ugh... please don't eat tofu. Make sure soy is fermented first, like tempeh and natto (you can make your own for cheap). Miso is good too, and if not pasteurized also a good probiotic food. But tofu only with foods naturally high in minerals, and only if your thyroid doesn't mind some heavy suppression and you're the gender that is ok with large dose of phytoestrogens (i.e. they can't tell us that menopausal women benefit from eating soy for phytoestrogens and in the same breath suggest MEN eat it too, they are males, for crying out loud, their lack of period is not caused by drop in female hormone levels - that's mine "Ever Wonder...??" moment)

Disclaimer: I know it's controversial topic. Do your own research. Or not. I LIKE tofu, and I LOVE the taste of soy milk (but 2x 6 oz cups a day drains all my energy in a space of a week) and my male friend who stopped eating it, misses it (since he can't digest meat)
